The windows of most types of habitable vstructure arefrequently opened and closed, and in certain types of structures it is essential that the windows be so constructed that a in addition to being readily and easily opened and closed, they be firmly sealed in closed position in order that during bad weather conditions, they will exclude, wind, water and other objectional manifestations of the elements. This essential is particularly important in the case of ships and other similar transportation vehicles, and it is to a window for such structures that my invention relates.

lVindows of traveling conveyances are subjected to conditions more severe than are those in stationary'buildings. This is particularly true in the case of ships, the windows of which are subjected, especially during storms, to severe conditions, sincethey are at times completely submerged in water. Under such conditions, it is essential that the windows be so constructed as to prevent the ingress of water to the interior of the ship and between the walls ofthe structure.

By my invention, I am enabled to construct a window which is readily and easily opened and closed, and which may: be firmly sealed to exclude the objectional elements of'nature. I employ a construction in which the window-pane is slidably mounted between two window-frame members which aremovable laterally with respect .to each other so that the window-pane may-be firmly clamped therebetween. V

An advantage of my construction is the fact that the window-pane may be firmly clamped between the frame members in any position of its movement.

A feature of myinvention is the provision of an interlocking device which, upon actuation of the means for clamping the windowpane betweenthe frame members, is operative to lock the window-pane traversing means. I

Specifically, I employ; a window construction in which there are two frame members, an outer frame member which is adapted to be secured to the side of the structure in which 1 the window is placed, and an, innerframe Two shafts, parallel to the planes of the frame members, are journaled between the latter in bearing brackets secured to the inner surface of theouter frame member. The shafts extend across the frame members,

member spaced laterally therefrom. A gasone above and one below the window open-' ings therein. To these shafts, which are connected together, for synchronous operation, theinner frame member is connected by means of eccentrics and cooper. ting eccentric straps whereby rotational movement of the shafts is translated into lateral movement of the inner frame member. The shafts may be rotated to move the inner frame member laterally by-meansof a handle provided for that purpose. Between the inner and outer frame members, there is provided a guideway which is movably supported 'by the outer frame member for lateral movement with respect thereto. A frameless window-pane is slidably mounted in the guideway, and traversing means are provided for raising and'l-o'weringthe window pane in the guideway. An interlocking device is provided which is operative to. lockthe window-pane traversing means upon movement of the inner frame member to clamp the windowfpane against the gasket in the "outer frame member.

Other'features and advantages of' my invention will be apparent from the following particular description of one embodiment of my invention taken in connection with the accompanying drawings in which:

taken on the line 66 ofFig. 1.

Fig. 6 is an enlarged fragmentary section in the drawingsthem. is illustrated a. winflow embo yi g my i en on e'win ow shown comprises an outer frame member 1 and an inner frame member 2. The outer member '1 is adapted to be secured to the side of the structure in which the window is placed and when used in ship construction, maybe secured to the plates 3 thereof. This frame member is provided with integral out wardly and inwardly extending flanges 5 and .6 respectively defining the window opening therein. To the inner'end of the inwardly extending flange 6, a gasket 7 is secured which extends completely around the window openingin the frame member. The gasket may, as shown, be dovetailed into' a groove 8lprovided therefor in the end of the flange 6. The inner frame member'2 which issupported in spaced relation to the-outer frame member'lis provided with an outwardly extending fiange 9 definingthe window open- ,ingth'erein, the end of the flange 9 being bent inwardly at a right angle parallel to the planes of the frame members and in alignment with the gasket? secured to the outer frame member 1. 1

Two shafts '10 and 11 extend across'the frame members 1 and 2, parallel to the planes thereof, one above the upper portion of the ifiange 9 defining the upper edge of the win- 'dow opening in the inner frame member 2,

and the other below the lower portion ofthe flange-9 defining the lower edge of'the windowopening in the inner frame member 2. The shafts 1O andllaref journalednear their ends in" bearing brackets 12 secured to the inner surface of the outer frame member 1. Corresponding ends of the shafts '10 and 11 extend'throughthe bearing brackets 12, and have cranks 13 ,securedon the extended ends 7 thereof. "The cranks 13 are connected to- 'gethe'r by a connecting rod14 so that rotation of'one shaft is transmitted, through the cranks and connecting rod, to the other shaft.

Intermediate the ends of the shafts, adjacent each bearing bracket 12, eccentrics 15 are secured to the shafts. Cooperating with each eccentric, there is an eccentric strap 16 which i has a threaded stud 17 formed integral there-- with. The studs 17 extend through openings provided therefor in the inner frame member 2 and are held therein by nuts 18 acting against the inner surface of the frame mem- ,ber 2, the frame member being held against thev nuts'18 by. convolute springs 19 inter- .posed between the-eccentric straps and the is translated, into lateral movements of the inner framemember 2. 7 Rotational movem-ent'may outerisurface of'the frame member. Thus, rotational movement of the shafts 10 and 11 he imparted to thesha-fts 10 and 11 toicontrol the; position of the frame member 2 through the follow- 1 ing train of mechanism: Near the crank 13 on V the lower shaf-tlll there issecured agear 20 "which meshes with a gear '21 secured on the endof a short shaft 22 which'is journaled at one end in a bearing bracket 23 andextends, at the other end, through a face plate 24. On the end of the shaft 22 extending through the plate 24:, there is secured a handle 25 for rotating the shaft 22. Thus, movement of thea handle 25 is transmitted tothe shafts 10 an 11.

Between the outer and inner frame members 1 and 2,-a window-pane guideway is supported. The guideway comprises a channel shape cross piece 26 which extends across the frame members, parallel thereto, above the flanges defining the openings therein. The length of the cross piece 26 is such that the ends thereof extend beyond the flanges on the frame members; To each end of the cross piece 26, a depending channel shape member 27 is secured. The guideway is supported by brackets 28 secured to the cross piece 26. by means of machine screws 29, the

brackets. 28 being slidably supported by 'sitioned .by a clamp member 32 attached to the lower edge thereof. The clamp 32 may desirablyv consist of a'channel-shape mem-- ber asshown, a packing strip 33 beinginterposed between the glass window-pane and the metal. For raising and lowering the window-pane, a vertical traversing screw 34 is provided and is rotatably mountedat its lower end in a bearing 35 and at its upper end in a bearing 36. A nut37 cooperates with thescrew 34. The nut 37 is provided with an integral collar 38 'atthe lower edge thereof, and with an internal hook member 39. A link member 40 having integral projecting arms 41 which are adapted to cooperate with the collar 38 on the nut and anopening '42 which is adapted to cooperate with the hook member 39 of the nut, is secured to the clamp member 32 in which the loweredge of the window-pane 31 is secured;- On the upper end of the screw 34, there-is secured a bevel gear 43 which meshes with a bevel gear 44 secured on one endof a sha-ft 45journaled in bearing brackets 46 and 47. A

second, bevel gear 48 is secured on the opposite end of the shaft.4 @5 and meshes with a bevel gear 49, secured on a short shaft 50 which is journaledat one end in the bearing bracket 23 and extends at the other end through the aforeme-nti'oned face plate24. On theend of the shaft 50 extending through the face plate 21, there is secured a, handle 51- by means, of which the shaft 50, and,

through the train just described, the screw 34, may be rotated. Rotation of the screw 34, by means of the nut- 37, raises or lowers the window-pane 31 in the guideway depending upon the direction of rotation of the screw.

On the shaft 22, which may be rotated to move the inner frame member 2 laterally to clamp the window-pane between the frame members 1 and 2 against the gasket 7 in the outer frame member, there is secured, immediately behind the face plate 24, a spur gear 52. The gear 52 meshes with a gear 53 secured on a stub shaft 54 extending through the face plate 24 and having secured on the end in front of the face plate a cam 55. The cam 55 is adapted to cooperate with a cam 56 having a plurality of complementary cut out portions 57 secured to the shaft 50 of the window-pane traversing mechanism. Thus, when the handle 25 is rotated to clamp the window-pane between the frame members 1 and 2, as shown in Figure 5, the "cam 55 is rotated so that the high portion thereof enters a cut out portion 57 in the cam 55 and thereby locks the shaft 50 which controls the raising and lowering of the window. This interlock prevents movement of the window-pane when it is clamped against the gasket 7 and thereby preserves the gasket which might be injured if the window-pane were forced when clamped against the gasket.

From the above description of the embodiment of my invention illustrated in the drawings it is evident that a window constructed in accordance with my invention may be readily and easily opened and closed, and also may be securely sealed to effectively exclude the elements.

It is obvious that various changes may be made in the embodiment shown in the drawings and above particularly described within the principle and scope of my invention as expressed in the appended claims.
